Method Detail

getFlows

public Collection<Flow> getFlows()
Specified by:
getFlows in interface FlowHolder
Returns:
the flows

handle

public FlowExecutionStatus handle(FlowExecutor executor)
                           throws Exception
Description copied from interface: State
Handle some business or processing logic and return a status that can be used to drive a flow to the next State. The status can be any string, but special meaning is assigned to the static constants in FlowExecution. The context can be used by implementations to do whatever they need to do. The same context will be passed to all State instances, so implementations should be careful that the context is thread safe, or used in a thread safe manner.

Specified by:
handle in interface State
Specified by:
handle in class AbstractState
Parameters:
executor - the context passed in by the caller
Returns:
a status for the execution
Throws:
Exception - if anything goes wrong

isEndState

public boolean isEndState()
Description copied from interface: State
Inquire as to whether a State is an end state. Implementations should return false if processing can continue, even if that would require a restart.

Specified by:
isEndState in interface State
Returns:
true if this State is the end of processing
